Showing Questions of 4

What is the tubing size needed for the unloader? 1/4", 3/8", 5/16"?

A: These are made for standard 1/4" o.d. tubing.

What is the voltage range for the input coil voltage? Will it work with both 120 VAC and 230 VAC?

A: There is no coil to apply voltage to. These are controlled by a diaphragm which activated the contacts in relation to pressure. The contacts are rated for both 115 or 230 at the current limits in the specifications.

does this switch have an unloader built into it or would I need to install an unloader on the unloader port?

A: It does have the unloader valve. Just needs a copper line running to the line between the compressor head and the check valve as the air enters the tank.

Is this 3 Phase?

A: This has only 2 sets of contacts instead of 3 that would be needed for 3 phase motors.
